Wearable electronic textiles (e‐textiles) have emerged as a transformative technology revolutionizing healthcare monitoring and communication by seamlessly integrating with the human body. However, their practical application has been limited by the lack of compatible and sustainable power sources. Various energy sources, including solar, thermal, mechanical, and wind, have been explored for harvesting, leading to diverse energy harvesting technologies, such as photovoltaic, thermoelectric, piezoelectric, and triboelectric systems. Notably, 2D materials have gained significant attention as attractive candidates for energy harvesting and storage in e‐textiles due to their unique properties, such as high surface‐to‐volume ratio, mechanical strength, and electrical conductivity. Textile‐based energy harvesters employing 2D materials offer promising solutions for powering next‐generation smart and wearable devices integrated into clothing. This comprehensive review explores the utilization of 2D materials in textile‐based energy harvesters, covering their preparation, fabrication, and characterization strategies. Recent advancements are highlighted, focusing on the integration of 2D materials and their practical implementations, shedding light on the performance and effectiveness of 2D‐material‐based energy harvesters in e‐textiles, and highlighting their potential as a sustainable alternative to conventional power supplies in wearable technologies.

Recently, design and fabrication of platinum free counter electrodes have received enormous attention of the scientific community. In this work, we have fabricated manganese dioxide/reduced graphene oxide (MnO2@Gr) counter electrode based DSSCs. Hydrothermal method was utilized for the synthesis of MnO2@Gr. Further, X‐ray diffraction technique (XRD), scanning electron microscopy (SEM), and energy dispersive X‐ray spectroscopy (XPS) were employed as physiochemical characterization technique. Surface structural investigations showed that MnO2 has rods like surface morphology which are attached with Gr. The fabricated DSSCs demonstrated good open circuit voltage (Voc) and reasonable efficiency of 0.72 V and 5.87 %, respectively.

Transition-metal dichalcogenides (TMDs) have recently emerged as highly appealing and efficient options for electrodes in dye-sensitized solar cells (DSSCs), effectively substituting the scarce and expensive metal platinum (Pt). In this work, nickel telluride (NiTe 2 ) quantum dots (QDs) were effectively used as a counter electrode for DSSCs by providing a sustainable alternative to the scarce platinum (Pt). The DSSC based on NiTe 2 QDs shows a power conversion efficiency (η) of ∼8.06%, which is comparatively better than exfoliated NiTe 2 (η ≈ 6.58%). The density functional theory (DFT) was employed to comprehensively understand the underlying mechanisms involved in the charge transfer between the QDs and the electrolyte species. The outcomes demonstrated the benefits of creating diverse structural configurations designed to enhance interfacial transport, ensure an even distribution of active facets, and improve the electrocatalytic performance in the DSSC process.
